Abstract (en)
A road surface reinforcing material consists of a hexagonal mesh which is made up from sections (3) of plastics strip with a wall thickness of between 3 and 8 mm and preferably 4-6 mm. The height of each section is between 1 and 5 cm and preferably 2-4 cm. Each mesh section has sides measuring between 5 and 25 cm, and preferably 8-12 cm. The sections have walls which converge towards their lower edges and are joined together by interlocking clips (7,11). The sections are made from polypropylene and produced by compression or injection moulding.
